Who Gives A Fish Forums

Thanks for the tips, everyone. I'll try root tabs and adjust the light. Didn't realize gravel was such a problem.

My plants keep dying even though my fish are fine. I have a 20 gallon tank with a basic LED light, gravel substrate, and a HOB filter. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. What am I doing wrong?
